Henry’s Fork 9-1-2011

We are all greatly interested in effects of Ashton Dam construction on the river below.  It appears that water will continue to be released until late next week in order to get the reservoir water level down 17 feet for work to be performed.  Therefore look for silt to be released through this time frame and impact river clarity at least as far downstream as the Chester Dam backwaters.  So far it appears that released silt is within expected amounts.  The Henry’s Fork Foundation (www.henrysfork.org) posts pictures of the river and is monitoring the impacts on it.

On the upper river around Last Chance and the Harriman reach, PMD spinner falls are bringing AM action, and terrestrial insect patterns bring action during daytime hours.  Have you ever twitched a hair mouse around grassy banks here around twilight?
